Showing quad wireframe when displacement is on

TLDR - a quad wire frame shows up on my mesh when displacement map is on

I am working on a material in designer.  Brought textures into marmoset setup material using height displacement.  I subdivided a sphere in blender and imported that in.  For some reason I see a quad wire frame over my entire object when the displacement map is on.  When I turn it off the wire frame goes away.  The wire frame is not representation of my mesh as it is highly tessellated.  When I view the height map.  It does get brighter darker depending on the position of the hdri.  Any Ideas?  thankyou!!

there are no wire frame lines in it.

so it seems to have something to do with the blender sphere I subdivided, if I bring in the default sphere from designer it doens't show this.  I don't use blender much so maybe some setting I have in there that shows it, not sure, very odd.

Make sure the sphere is smoothed, if it has hard edges, it may split at the edge seams.
